How can I determine where Log4j selects its configuration from

Is there any way to find out where Log4J selects the configuration file? I tried changing my log4j.xml and the changes were not reflected in the behavior of Log4j. I deleted log4j.xml and funny enough, Log4J is still working with the old behavior. Therefore, he should select the configuration file available in my namespace. But the question is, how can I find out which one. Is there any way to do this? there are many different dependencies on jars, etc., so one of them should contain log4j.xml or log4j.properties, which overrides my changes. Any ideas?
